What is the difference between pipe section,hot-finished

I was reading a steel catalog and saw that it categorizes steel sections separately into pipe section,hot-finished circular hollow section,and cold formed circular hollow section.Given the same design strength,for example S355,is there any fundamental differences when designing a section of say,610mm depth and 10mm thickness,using steel Steel Hollow Sections- Gemina internationalSquare Hollow Sections.Typically made to A500 standards in Grade A,B,and C metals,they are also found as A513 and HSLA grades 50 and 70 sections.They are formed as squares or rectangular tubes through hot rolling and often called HSS or hollow structural sections.Steel Hollow Section The preferred choice of architects At Kloeckner we offer 3 different grades of Hollow Sections from several different manufacturing processes.Our comprehensive stock includes both Hot and Cold formed Hollow Sections in material grades S235,and S355J2H and we also have access to non-standard sizes and other tubular products through our European subsidiaries.

hot and cold formed hollow sections#0183;Cold rolled or cold formed steel has a smooth,shiny finish with an oily texture that is free of rust or scale so it can easily be painted or chromed.The dimensions of the final product are more precise and square,with a sharper edge,and cold rolled steel sheet can hold tighter tolerances than hot rolled when machined or otherwise fabricated.MAIN DIFFERENCES IN THE MECHANICAL PROPERTIESHot finished hollow sections are characterized by the better flexure curve (a),cold finished hollow sections corresponds to curves b or c depending on the buckling stess used for calculation.This means that hot finished sections can tolerate higher stress of flexure.John Bell Pipeline Structural Hollow Section - John Bell John Bell Pipeline Equipment Company Ltd now supply Hot and Cold Formed Hollow Section.Available in Circular,Square and Rectangular form.Sourced from our parent company National Tube Stockholders Ltd (NTS) with 100,000 tonnes of stock ready to go for quick delivery.
